Abstract

The disclosure of this application is directed to a downhole tool comprising a central element/member and a sleeve that is rotatably and orbitally disposed around the central element/member. The sleeve rotates and orbits around the central element/member responsive to fluid flowing through the downhole too. The disclosure is also related to a method of advancing the downhole tool in a well by flowing fluid through the tool.

First claim

What is claimed is:

1. A method, the method comprising:
pumping fluid to a downhole tool to rotate and orbit a sleeve around a central member to advance the downhole tool into a wellbore, the central element having an outlet disposed therein to permit fluid to flow from a passageway disposed through the central element into an annulus area; and the sleeve rotatably and orbitally disposed around the central element, the sleeve rotates around the central element responsive to fluid flowing through the downhole tool and includes an exhaust port disposed therein uphole from the outlet disposed in the central element to permit fluid to flow from the annulus area to outside of the downhole tool, the annulus area disposed between the central element and the sleeve, the downhole tool having a top sub for connecting the downhole tool to other tools disposed above the downhole tool and a bottom sub for connecting the downhole tool to other tools disposed below the downhole tool.

2. The method of claim 1 wherein the downhole tool is included with other tools in a bottom hole assembly (BHA) and the downhole tool is used to advance the BHA into the wellbore.

3. The method of claim 1 wherein the central element has a rotor profile disposed thereon and the sleeve has a stator profile disposed on the inside to cooperate with the rotor profile to force the sleeve to rotate and orbit around the central member as fluid flows from the passageway, through the outlet in the central member, between the central member and the sleeve and out of the exhaust port.

4. A method, the method comprising:
pumping fluid to a downhole tool to rotate and orbit a sleeve around a central element to advance the downhole tool into a wellbore, the downhole tool comprising:
a top sub for connecting the downhole tool to other tools disposed above the downhole tool;
a bottom sub for connecting the downhole tool to other tools disposed below the downhole tool;
a central element;
a sleeve rotatably disposed around the central element, the sleeve rotates around the central element responsive to fluid flowing through the downhole tool; and
at least one side-load apparatus to force the sleeve into an inside portion of a casing to engage the casing.

5. The method of claim 4 wherein the side-load apparatus includes a casing engaging member for interacting with the inside portion of the casing and a driving element for forcing the casing engaging member into the inside portion of the casing.

6. The method of claim 5 wherein the casing engaging member is a roller or wheel.

7. The method of claim 5 wherein the driving element is a hydraulic piston that uses the fluid pressure in the tool to force the casing engaging member into the inner portion of the casing.

8. The method of claim 5 wherein the driving element is selected from the group consisting of a compression spring, a hydraulically actuated arm, mechanical linkage, a drag block device, and a fluid jet.
